LANTERN.

SPECIFICATION forming part of Letters Patent No. 549,099, dated November5, 1895.

Application filed July 8, 1895. Serial No. 555,299. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES BERGENER, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Lanterns; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, and tothe reference-letters marked thereon.

My present invention relates to lanterns, particularly of that type inwhich the oil pot is attached to the base of the lantern and isremovable with the base from the upper globecarrying frame; and it hasfor its object to improve the construction of the base portion and alsothe construction and operation of the devices for fastening these partstogether, the novel features being pointed out in the claims at the endof this specification.

In the drawings, Figure 1 is a side elevation of a portion of the bottomof a lanternframe; Fig. 2, a longitudinal sectional view through thebottom of the lantern-frame, showing the base carrying the oil-potapplied thereto, but not turned so as to cause the locking of thebayonet-joint fastening; Fig. 3, a perspective view, partly in section,of the base of the lantern, showing the fastening devices; Fig. 4, ahorizontal sectional view on the line 50 x of Fig. 2; Figs. 5 and 6,sectional detail views showing the operation of the catch at variousstages.

Similar reference-letters in the several fig ures indicate similarparts.

A indicates the bottom ring of the ordinary railroad-lantern frame, Bthe guards, and C the globe. This ring A is provided, as usual, near itsbottom with the bead or shoulder A, and is also provided near its lowerend with thelocking-pins a. Secured upon the inside of the ring A is aspring D, fastened at cl, having its outer end projecting through thering formed into an operative button D, and preferably beneath the beadA on the ring it is provided with an inclined projection D E indicatesthe bottom of the lantern stamped from a single piece of metal andhaving the depressed central portion E, to which is secured the oil-potF, preferably by soldering. The vertical walls of the depressed portionE are provided on opposite sides with slots e, having the portions 6,extending laterally in opposite directions, and the'slots in the upperor rounded portions of the base E 5 5 are sufficiently long for theaccommodation of the locking-pins a on the bottom of the ring A.

The projection D on the spring D and the pins a and slots 6 e are soarranged relatively that the following operations can be accomplished:

WVhen it is desired to attach the bottom to the lantern-frame, theoperator simply inserts the oil-pot into the ring A, causing the pins ato enter the slots e, and at the same time the inclined surface of theprojection D on the spring engages the upper edge of the base and ispressed backward, as shown in Fig. 5, the pins to passing to the bottomof the slots (2. The lantern-frame and the base are then rotatedrelatively to cause the pins (1 to pass into the horizontal portions eof the slots in the base until the projection D enters the vertical slote, when it will spring out and' prevent the relative movement of thebase and lantern-frame in either direction. To cause the unlocking ofthe base and the removal of the oil-pot, it is only necessary to pressthe spring D backward and to move the ring and base in the oppositedirection until the pins are in line with the vertical portion of theslot 0.

By means of the construction shown I provide a more durable base portioncarrying the oil-pot, forming it of a single piece of metal stamped andcompleted at one operation and with no locking devices projecting abovethe top of the base, and also provide a single spring, which can becheaply made and will accomplish the locking operation in a simple andefficient manner.

It will be understood that the same locking devices could be employedeven if the base were not formed integrally with the depressed 9 5cup-shaped portion, as the vertical walls could be replaced by a collarattached to the base otherwise than as shown.

I claim as my invention 1. In a lantern, the combination with the basering of the lantern-frame, the projecting pins, the laterally movablespring-catch hav ing the beveled face, of the removable lantern bottomhaving vertical Walls provided with the angular slots with which thepins and catch cooperate, substantially as described.

2. I11 a lantern, the combination with the base ring of thelantern-frame, and the projecting pins, of the base formed integrallywith the central depressed portion, having the angular slots in thevertical Walls of the depressed portion, and the spring-catch having theprojection engaging the vertical slots in the base, substantially asdescribed.

3. In a lantern, the combination with the base-ring of thelantern-frame, of the base composed of a single piece of sheet materialformed with the central depressed portion, the oil-pot arranged in saidcentral portion, and locking devices between the base-ring and theCHARLES BERGENER. Witnesses:
